    Newcastle Village and District Historical Society Newsletter Spring 2017 - Issue # 127 PRESIDENT’S REPORT e are beyond the middle of May, so let’s hope we will be blessed with more pleasant weather and higher tem- peratures ! On an unhappy note, we just received word from the Federal Government that our application for a grant has, W for the second year in a row, been denied. This, despite encouraging words from Federal bureaucrats, after the denial last year, that we should apply once again. Reasons for the denial are not provided so the whole thing remains a mystery – this in the face of a lot of work in preparing our applications with great precision and exhausting detail in each of the two years. The grant would have enabled your Society, working with Durham College, to electronically capture our records ( histori- cal letters, agreements, wills, photos, and so on ), then to make our data more readily available to scholars, students and the general public. We will, of course, soldier on and explore other options to fund this worthwhile project, including the possibility of finding corporate sponsors. And, while other Government grant opportunities will be looked at, we will attempt, as far as possi- ble, to seek some assurance that any other applications have a reasonable chance of success and not simply serve as a “make work” projects for bureaucrats. Our plans are moving ahead for HERITAGE DAY, an event created and hosted by your Society. It will be held in the main hall of the Newcastle Community Hall from 10AM until 3PM on June 25, 2017.

The transportation corridor includes a highway component and a transitway component (i.e. a dedicated corridor for transit). The MTO is the project proponent for the 407 East Transportation Corridor Project (the Project). ES.2 Purpose of this Draft Comprehensive Study Report The Canadian Environmental Assessment Agency (CEA Agency) has delegated the preparation of this draft Comprehensive Study report, and certain procedural aspects of public participation in its development, to the MTO. The purpose of this draft Comprehensive Study report is to provide, from the proponent’s perspective, the information, analysis and conclusions relevant to an eventual determination by the federal Minister of Environment on the likely significance of adverse environmental effects from the project.

Ryan Pfeiffer / Metroland An introduction to Durham Region’s natural environment People are often surprised by the sheer size of Durham Region. It spans nearly 2,500 square kilometres, and its beauty doesn’t stop at the waterfront that five of its municipalities enjoy. 22 Eco Durham Introduction Durham is abundant with natural features: creeks that flow from the Oak Ridges Moraine, the shores and sandy beaches of Lake Ontario, the forested areas of Durham Regional Forest that sits just south of Uxbridge, Altona Forest in Pickering, and the wetlands of Second Marsh in Oshawa, to name a few. A short walk or drive in the region offers plenty for nature enthusiasts to see. “There’s one provincial park and several conservation areas and there’s just lots and lots of areas,” said Lois Gillette, president of the Durham Region Field Naturalists. The Region of Durham explains on its website that woods, headwaters, ridges, hollows and rolling farmlands make up a diverse landscape, and in the north, Durham spreads into the lakelands of Simcoe, Scugog and the Kawarthas.
